This article examines the non-discrimination provisions of the European Convention on Human Rights in relation to social security law. There is a now a broad power of review under the ECHR as most social security payments fall within the scope of the Convention. There is also a more flexible approach to the grounds upon which discrimination can be challenged under Article 14. However, it is suggested that the European courts may need to adopt a more nuanced (or proportionate) approach to equality review rather than a binary approach.
